How can the encoding of special characters like Unicode 084F impact the display of a PHP website on different devices?

Special characters like Unicode 084F can impact the display of a PHP website on different devices if the encoding is not handled correctly. To ensure proper display across devices, it is important to use a consistent character encoding, such as UTF-8, throughout the website. This will help prevent issues with special characters not displaying correctly or appearing as garbled text.

// Set the character encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');
